 workflow::role::get_all_info_not_cached -workflow_id workflow_id

Defined in packages/workflow/tcl/role-procs.tcl

This proc is for internal use in the workflow API only and should not be invoked directly from application code. Returns all information related to roles for a certain workflow instance. Goes to the database on every invocation and should be used together with util_memoize.

Switches:
